Some things really confuse me. Conservatives continuously complained about inflation, so under Obama inflation has been so low that in 3 of his years there was no increase in the CPI-w. Prior to 1975 there was no increase in SSec benefits unless congress each year passed an increase. In 1972 GOP Nixon's proposal to stop the yearly game of passing increases was made into law with bipartisan support.

"The uncertainty of adjustment under present laws and the delay often encountered when the needs are already apparent is unnecessarily harsh to those who must depend on Social Security benefits to live.

Benefits that automatically increase with rising living costs can be funded without increasing Social Security tax rates so long as the amount of earnings subject to tax reflects the rising level of wages. Therefore, I propose that the wage base be automatically adjusted so that it corresponds to increases in earnings levels." Legislative history is here:

In the previous two cases where no COLA increase was given by the law, there was proposed legislation to give a bonus payment to seniors. And GOP votes killed that increase. https://votesmart.org/bill/votes/329...y#.VpKsdstIg5s

And this time there is a bill introduced by Sen. Warren D-Massachusetts to give an increase equal to the average increase of CEO's. So one party is trying to protect seniors from the use of the CPI-W and one is not. One party is responsible for no increase in your SSec in 2016, and one is working unsuccessfully to lessen the impact of the lack of a COLA.
